To all whom it may concern."

Be it known that l, FRANK RIEBER, a citizen of the United States, residing in the city and county of San Francisco and the State of California, have invented certain new and useful Apparatus for Extracting.

and inserting High-Tension Fuse-Plugs, of which the following is a specification.

My invention relates to high tension iu'se plugs and particularly to means for extracting the plugs from or inserting them in the high tension line.

An object'oi the invention is to provide instrument whereby high tension fuse plugs may he safely removed by the line man, without previously opening the'high tension line.

Another object of the invention is to provide such an instrument which is operable by one hand of the lineman to remove or in sert the fuse-plug.

Another object of the invention is to pro vide such an instrument which is simple and ged in construction.

the invention possesses other advantageous features, some of which, with the foregoing, will be set forth at length in the foll cwing description where l shall outline in full that form of the invention which l have selected for illustration in the drawings accompanying and forming part of the present specification. in said drawings l have shown one specific form of the instrument of invention, but it isto be understood that i do not limit myself'to such form, because the invention as expressed in the claims, may be embodied in a plurality of forms.

Referring to said drawings:

Figure 1% is an elevation of the instrument.

Fig. 2 is a vertical section of the instrument on a lar or scale, showing it in engagement with si h of the device bemgbroken away to reduce the size of the figure.

Fig. 3 is a vertical section of the head or tgie mstrmnent taken at right angles to ..i 2. v

he instrument comprises a clutch head 2 having a seat or socket therein which opens at one side of the-head and which is closedatthe other side. The upper portion of the Specification of Letters Patent.

socket is restricted in width by the overhanging sidewalls 3 and rear wall 4. The

handle 5 of the fuseplug fits in the socket and is held therein against'relative movement in a direction longitudinally of the head, by the overhanging walls, under which the enlarged end of the handle 5 engages.

lhe socket is open at the side, so that the head 2 may be readily slipped on or removed transversely from the handle.

Secured to the head 2 is a bar or handle 6 of insulating material, which is held by the lineman in one hand, as he removes or in serts the plug and the handle is of ample length to adequately protect the lineman. In order to prevent the head from becoming disengaged from the fuse plug, by a trans verse movement of one with respect to the other, I provide an abutment which is mov ahle into the socket at its open side, thereby closing said side against egress of the plug handle. The abutment is preferably formed as a movable retaining piece 7, which is movable into and out of a seat 8 in the clutch head. The retaining piece is secured to a rod 9 of insulating material lying ad acent and parallel with the handle and this rod 9 is provided on its lower end with a hand grip l2, partly surrounding and slid'ably engaging the handle. 'lhe rod 9 is also sultably guided in a bracket 13 secured to the handle. The retaining piece is preferably heveled on its inner side, or on that side which engages the handle of the plug so that it willoperate 1.0 wedge the plug handle tightly in the socket.

In 0 eration, the lineman grasps the device, h1s hand surroundin the exposed section of the handle 6 and a so thasemi-circular hand grip 12, which is then in its lower position. The clutch head is then moved transversely over the handle of the fuse plug and the lineman then slides his hand upward, movin the retaining piece into the socket, there y locking the plug inplace. The lineman then tightens his grip'on the handle, so that there will be no relative movement of the hand with respect to the handle and then pul s t e fuse plug from its seat. With the use of this instrument,

the fuse plug may be withdrawn or inserted with one hand, permitting the lineman to employ the other hand to sustain himself on v the pole.

I claim:

von which said head is mounted, and means arranged adjacent said handle for operating said locking device.

2. In an instrument for withdrawing or inserting high-tension fuse plugs having handles, a head having a socket therein opening on the side of the head and adapted to receive said handle, overhanging shoulders on said head constricting the end opening of said socket, a longitudinally movable looking device 1n said head adapted to lock said .handle in said socket, an insulating handle 1. In 'an instrument for withdrawing or handleof the fuse plug.

onwhich said head is mounted, a hand ip slidable on said handle, and a rod of insu atng device.

In an instrument for withdrawing or inserting high-tension fuse plugs havmg handles, a head having a socket therein opening on the side of the head and adapted to receive said handle, a handle of insulating material on which. said head is mounted, a retainin device seated. in one side of said head and movable into said socket adjacent its opened side, a hand grip slidable on the insulating handle, and a rod ofinsulating material connecting the retaining device and the hand grip w ereby movement of the hand grip alon the insulating handle moves the retaining evice to release or look the In testimony whereof, I have hereunto set my hand at San Francisco, California, this 13th day of June 1917,.
